Two new flavone C-glycosides from Trollius ledebourii.
CHEMICAL & PHARMACEUTICAL BULLETIN(2011)
摘要
Two new flavone C-glycosides, trollisin A (1) and trollisin B (2), along with seven known flavonoids, isoswertisin (3), isoswertiajaponin (4), orientin (5), 2 "-O-beta-L-galactopyranosylvitexin (6), 2 "-O-beta-L-galactopyranosyl-orientin (7), neodiosmin (8) and acacetin-7-O-neohesperidoside (9) were isolated from the flowers of Trollius ledebourii REICHB. The structures of the new compounds were elucidated based on spectral analysis, including MS, 1D- and 2D-NMR experimentation.
